Power Tool Commutator Solution
2022-10-20
Kommutatoren er meget udbredt inden for bilindustrien, husholdningsmotorer og elektriske værktøjer. Kommutatorens grundlæggende struktur er: inklusive kommutatorkobberpladerne jævnt fordelt på den ydre omkreds af kommutatorlegemet og kommutatorlegemet. Formet sammen er den kommuterende kobberplade forsynet med et stykke fod, som er implanteret i kommutatorlegemet og fast kombineret med kommutatorlegemet.
In order to strengthen the bonding strength between the commutator copper sheet and the commutator body, and improve the mechanical properties of the power tool commutator products, the most commonly used method is to improve the structure of the chip feet and set the reinforcement ring, and the improvement of the chip foot structure is the most ideal. The technical solution is to increase the size of the film feet. However, for power tool commutator products with small radial size and large number of commutation copper sheets, the size of its feet is strictly limited in both the circumferential and radial directions, and each adjacent commutation is strictly limited. The distance between the inner sides of the pins of the copper sheets will be very small. If the radial dimension of the pins is increased, the adjacent pins will easily touch when the commutating copper sheets and the commutator body are injected together. , resulting in a high rejection rate of commutator products after injection molding.
